Treatment of coke.

TREATMENT OF COKE.

No Drawing.

To all whom it may concern:

Be it known that we, BENJAMIN ELY and :ARTIIUR ROLLASON, subjects ofEngland, re-

incandescent or partially incandescent state,,

are covered with a layer of coke breeze, coke dust, coal ash, or othersuitable material, of suflicient thickness to exclude air and moisturewhile the cokes are slowly cooling down, during which the volatilesubstances con tained in the coke escape. The cokes, after coolingslowly with air and moisture excluded in the manner herein described,become softened and when employed as fuel in an open grate or a furnace,they will ignite and burn with a steady flame.

The softened cokes treated by our improved. method can be ground andused in the manufacture of electric carbons or blacking for foundrypurposes'or any other use for which soft carbon can be employed.

What We do claim and desire to secure by Letters Patent is,

Specification of Letters Patent. Application filed October 22, 1909.serial No. 524,044.

Patented Oct. 11, 1910.

l. The method of forming a fuel from coke which consists in withdrawingthe coke from the retort while in a heated state, covering the same witha layer of suitable cornlninuted material of sufficient thickness toexclude air from the coke, and permitting the coke to cool while coveredwith said 40 layer.

2. The method of forming a fuel from coke which consists in withdrawingthe coke from the retort while in a heated state, covering the same witha layer of suitable comminuted material of sufficient thickness toexclude air and moisture, and permitting the coke to cool while coveredwith the said layer. I

3. The method of forming a fuel from coke which consists in withdrawingthe coke from the retort while in an incandescent state, coverin thesame with a layer of coke dust of a su cient thickness to exclude airand moisture, and cool while covered with the said layer.
